Indy 426 Hemi Heads

Old elephants will die, and the legend will live on. Probably Indy's biggest challenge to date is designing new life into an almost forgotten normally aspirated engine. Integral cast in rocker stands, moveable rocker shafts, exhaust valve relocated, taller valve cover rail, .350 longer intake valve, raised intake and exhaust ports with superior air flow breeds new life in the redesigned legend head from Indy Cylinder Head.

Integral cast in rocker stands. If the valve geometry changes, shafts can be shimmed (Indy #426.11) to correct geometry
The cast in stands also make the head much stronger eliminating flex.
.350 longer intake valves make a raised intake port possible, air can be increased to the 500 CFM range
The Legend head is drilled for 16 bolt
Can be drilled for 10 bolt or custom
Exhaust ports can be ordered in raised or stock location, for stock engine compartments
Exhaust valve relocation makes it possible to use a 2.400 intake valve, with a 2.00 exhaust
Because of the raised ports, the valve cover rail has to be raised .500 making longer spark plug tubes necessary Indy (#426-17)
